IMPROVEMENT IN PLows. r

The S ,1:\`edule referred to in these Letters Patent and making partzof the same.

To all whom it may concern.-

.Be it known that we, D Avn A. STUBBLEFIELD and NYILLLAM H. Lusn, of the county of VYazoo, in the State of Mississippi, haveinvented a new and useful Improvement in Flows, oi' an improved mode of coupling plows; and do hereby declare that the followingis afull, clear, and exact description thereof, reference being had tov the accompanying-drawings, making 'part of this speGicatiOn, in which- Fgure 1 represents a top or plain view of our in- .vention, and j Figure 2 is a front view of the same, looking toward the rear, as indicated by the .arrows shown in both figures.

The nature'of our invention consists in providing ganglplows-with a. series. of perforated wooden or' metallic bars for the purpose of adj nstment, whereby the plows may be set at any requiredv distance apart, for the purpose of turning the earth either to or from the corn or other growingjcrop, asdesired.

To enable othersskilled in the art to-make and use ourv invention, we Willproceed to describe the con-1 struction and operation.

We construct our plow in any of the known forms, with the exception, that we employa series of perforated bars, asshown by A, B, and C, in the accompan ying drawings. These bars and handles are secured to the standards by means of screw-bolts provided withnuts ca a a, shown in figs. 1, 2, and 3.

The standards D D arev mortised to receive either end of the bar C, as clearly shown in the perspective View, Figuref'. '.lhe other two'bars are bolted loosely on to the beams E E and standards D D. v

The double-tree L is also provided vwith cuff-irons F F, so thatthe plow-beams may always be kept parallel distances-apart. i

The operation is so extremely simple that any farmer'can readily adj ust it to any required width, by,

simply removing the bolts g g in bars B and C, and standards D D, and the bolts gin bar A and beams E E, and the bolts g g in cuff-irons -F F. The working of tnepiow'maybeeither expanded or contracted by merely adjusting the bolts g g in bars A, B, and G, and vbolts' g g in culi-irons F F.

The plows are reversible from right to left, and 'vice versa, for barring off or bedding up. The couplingbars and bolts may b'e made of wood or metal.

VThe coupling-bars A B O, and double-tree L, may have any number of holes in which to place the bolts g, in order to widen or narrow the working of the plow.v

We do not claim, broadly, coupling plows, for that is old and Well known; but

What we do claim, and desire to secure by Letters Patent, isf- -The coupling-bars A, B, and C, standards D, beams E, and double-tree. L, cuiillirons F, and bolts g,vwhen the whole is combined, arranged, and .operated substantially as for the purposes set forth.

In testimony that we claim the foregoing invention of anew and usefulV improvement in plows, or a new mode of coupling plows, we have hereuntoset our l hands, this 9th day of July, 1869.
